MACHlNE FOR MAKING BRICK OR THE LIKE.

SPECIFICATION formingpart of Letters Patent No. 731,860, dated June 23, 1903.

Application filed June 13, 1902. fierial No. 111,531. (No model.)

To aZZ whom it may concern:

Be it known that we, THOMAS COLE and WILLIAM LAWES COLE, subjects of the King of Great Britain, residing at Park Road Iron Works, St. Anns Road, Burdett Road, Bow, London, England, have invented certain new and useful Improvements in Machines for Making Brick or the Like, of which the following is a specification.

The object of this invention is to so con struct a machine that a mold can be filled with the necessary material from a hopper or other filler, a head-piece being then placed on top of the material to form the top of brick. The material is then jogged or shaken. to be solidified and settled in the mold and get rid of any air-bubbles which may be created during the filling of the mold, the mold being afterwardplaced in a frame or casing, which is actuated to grip the sides and support the back and front of the mold, and the material pressed by a press-head, the mold being afterward removed and laid on its side and opened out, so that the brick or slab can be removed on one of the sides of the mold,

and so preserve its shape.

Our invention will be clearly understood from the following description, aided by the accompanying drawings, in Which- Figure'l is a front view, and Fig. 2 a plan, of our apparatus, the side tables being broken away. Fig. 3 is a side view of the mainportion of the machine, the side tables being reside elevations of the jogging-table. .Fig. 6 is a part sectional elevation showing the cranks for moving the pieces for gripping the moldyFig. 7, a plan of same, showing also the handle and the back and flap in dotted Fig. 8 is a view of the crank mechanism for operating the gripping devices.

Fig. 11 is afront view of the arresting-lever released from the foot-pedal ready for the pedal to be operated. Fig. 12 isa front view of the mold in a complete form. Fig. 13 isa side section, andflFig. 14 a sectional plan, of the mold.

For the purpose of this invention we construct standards 1 for containing the principal operating parts, with tables 2 3 on either side, and from a gear-wheel 4, Fig. 2, we drive by chain 5 or otherwise twoor more ratchet or other wheels 6, Figs. 1, 4, and 5 capable of giving a jogging motion to a plate or slab 7, onwhich the mold is stood for filling, the jogging thoroughly settling and amalgamating the material and disposing of any airbubbles which may be contained therein. The mold, Fig. 12, being filled to thedesired height and having been sufticiently acted upon by the jogging-slab, the cover is then placed therein and the mold removed to between thestandards 1 and placed in the frame 8. The portion of the tables between and in plate or. wall 10. A handle or lever 11 is now actuated, and movable pieces 12 are brought by cranked levers 13 and rods 14 or gear into contact with the ends of the mold and angled edges 15 of the folding-flap portion 9 of the tables, so as to grip and engage same and form a frame to the mold for resisting all strain of the press-head 16 and preserving the shape of the mold. A foot or hand lever 17 is now actuated and the press-head 16 lowered to compress the contents of the mold and expel surplus moisture. This lowering andreturning of the press-head 16 is only effected after pressure of the foot-lever 17, the press-head 16 being connected by rods 18 to crank-disks 19 on the shaft 20, so that the lever 17 on being pressed operates a Wedge-cam 21 and moving it clear of a clutch 22, so that same can engage with the driving-wheel 23 by a spring for actuating the press-head 16, the wedgecam 21 returning to its normal condition for engagement in an opening in the clutch, so that by the time the press-head 16 has been lowered and raised the clutch 22. will have become again engaged with the wedge-cam 21 and be shifted out of gear with the drivingwheels 23, whereby the action of. the presshead 16 will be stopped, this being further insured from moving by a permanent friction or other brake 24on the crank-disk 19. The operator now reverses the first-mentioned lever 11 and frees the table -flap 9 and causes the side pieces 12 to retire. He now lowers the flap 9, and the stop 24 on one weight of the balance-lever 39 acts on the lever 25.

and automatically places its end under the foot-lever 17, which actuates the clutch 22 and effectually prevents the clutch mechanism being thrown into gear while the front flap 9 is down, so that the press-head cannot be actuated until the flap 9 is raised, and by operation on another foot-lever 26 operates a piece 27, forming partiof the resistance-wall 10, and this strikes the bottom of the mold and pushes it out, so that on the operator catching hold of the key of the mold he can easily remove the mold from the framing. This knocking or kicking of the box, in addition to rendering the box easy of removal, somewhat frees the sides of the mold from the material and prevents sticking, so that the brick or slab when sufficiently dry can be readily removed. The mold hereinafter described is then passed onto the table 3 to another operator, who removes the tube and the key of the mold, lays the mold upon its side, preferably upon a raised portion of the table, unlocks the edges, and folds same back, then removing the top side and afterward the edges, so that the brick or slab is lying on the now bottom side plate,which,with the brick, can be lifted by the operator and carried to another part of the building for proper drying and setting,thus keeping the brick or slab in its proper shape.

The mold Fig. 12 is made with the two ends 29 '30 hinged to the bottom 31, the interior surfaces conforming to the shape of the edge of the brick intended, the sides 32 33 of the mold being made of sheet-iron and fitting in recesses in the edges of the ends, these being kept in place by a wire loop 34 or other means. The sides 32 33 of the mold are provided with holes 35, through which'a key 36 is passed to engage the sides 32 33 and prevent bulging outward while on the jogging-table 7, the

handle of the key 36 acting as a means for assisting the operator in manipulating the mold on the table. A tube 37 is fitted to the bottom of the mold and engages the other end of the mold after the required quantity of cement or concrete is placed therein. The tables are provided with rollers 28 for easy manipulation of the molds.

The tube 37 maybe dispensed with and the inside of the edges, bottom, and top or sides of the mold be of a shape to suit the forma-' tion of the brick or slab whether of the ordinary or of the interlocking kind.

The fixed wall or plate 10 of the frame Sis detachably connected to said frame and can be readily removed for affixing of another of ters Patent, is

2. In a machine for making brick and the like, a reciprocating press-head, a lever controlling the operation of said press-head, a mold-receptacle having a stationary back, adjustable sides and a folding front, said folding front being provided with a counterweight, mechanism for locking said mold-receptacle in closed position, and means operated by-the opening of said mold-receptacle for locking said lever to preventthe operation of said press-head.

3. In a machine for making bricks and the like, a mold-receptacle, havinga folding front to permit the insertion and withdrawal of a mold, a press-head arranged to descend into said mold-receptacle, a lever pivoted to the rear wall of said receptacle, for pushing outward the mold contained therein,-and means for operatingsaid lever.

45. In a machine for making bricks and the like, an operating mechanism, a reciprocating presser-head, a mold-receptacle, a joggingtable, and ratchet-wheels actuated by said operating mechanism, for operating said jogging-table.

5. In a machine for making bricks and the I like, an operating mechanism, a reciprocating press-head, a mold receptacle comprising a stationary back, adjustable sides and a folding front, said folding front having a counterweight, a lever-actuated mechanism for locking said mold-receptacle in closed position, a clutch mechanism for actuating said press-head from said operating mechanism, a lever controlling said clutch mechanism, means for locking said last-mentioned lever when said mold-receptacle is opened, and a joggingtable actuated by said operating mechanism.

In testimony whereof We have hereunto set our hands in presence of two subscribing witnesses.
